What is Intel Hyper-Threading Technology?
How it works
Intel Hyper-Threading Technology (HTT) is a processing feature that enables multiple threads to be executed simultaneously on a single core of a processor. This is achieved by creating multiple virtual processors within a single physical processor, which can then be scheduled and executed independently.
Dual-Core Processors
In dual-core processors, there are two physical cores on a single chip. Each core has its own set of execution units, which can execute instructions independently. HTT can be enabled on both cores, allowing four threads to be executed simultaneously.
Multi-Threading
Multi-threading is a programming technique that allows a single program to be divided into multiple threads, each of which can be executed independently. When HTT is enabled, each thread can be scheduled and executed on a separate execution unit within a core, resulting in improved performance.
It’s important to note that not all programs can benefit from multi-threading, as it depends on the specific application and the way it’s designed. Additionally, enabling HTT can increase power consumption and generate more heat, which may have implications for system stability and lifespan.
